как преобразовать время из локального в UTC?

# Set CLOCK to "UTC" if your hardware clock is set to UTC (also known as
# Greenwich Mean Time).  If that clock is set to the local time, then 
# set CLOCK to "local".
# Note that if you dual boot with Windows, then you should set it to
# "local" because Windows always sets the hardware clock to local time.
CLOCK="UTC"
# Select the proper timezone.  For valid values, peek inside of the
# /usr/share/zoneinfo/ directory.  For example, some common values are
# "America/New_York" or "EST5EDT" or "Europe/Berlin".  If you want to
# manage /etc/localtime yourself, set this to "".
TIMEZONE="Europe/Minsk"
# If you wish to pass any other arguments to hwclock during bootup, 
# you may do so here.
CLOCK_OPTS=""
# If you want to set the Hardware Clock to the current System Time (software
# clock) during shutdown, then say "yes" here.
CLOCK_SYSTOHC="yes"
### ALPHA SPECIFIC OPTIONS ###
# If your alpha uses the SRM console, set this to "yes".
